Stellar Classifiion Astronomy

Harvard Classification In the late 1800s an astronomer at the Harvard College Observatory began to record stellar spectra using a method similar to the glass prism described above. The first star looked at was noticed to have gaps or breaks in the spectrum at specific points called absorption lines.

    The classification of Stars Atlas of the Universe. This system is referred to as the Morgan Keenan system. The Morgan-Keenan MK system is used in modern astronomy a classification system to organize stars according to their spectral type and luminosity class. The system was introduced by William Wilson Morgan and Philip C Keenan in 1943.

    In astronomy stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with absorption lines.Each line indicates an ion of a certain chemical element with the line strength indicating the.

The right-hand version indicates the same stars absolute magnitudes — how bright they would appear if they were all placed at the same distance 32.6 light-years from Earth. Absolute magnitude is a measure of true stellar luminosity.
